You're looking for a left join:

select 
    table1.name as left_name,
    table2.name as right_name
from
    table1
left join
    table2
on
    table1.name=table2.name

Then you can make the name bold when left_name eq right_name. right_name will be undef if the left_name doesn't occur in table2.

I suggest you read up on relational databases, foreign keys, natural vs. synthetic keys etc. Your model smells of denormalisation.
